I have decided that spinach is the new lettuce. A bag of it turns out to be a surprisingly versatile thing to keep in the fridge - toss a few leaves into miso and vegetable soup, or a tomato pasta sauce - it's madly good for you, and unlike lettuce, it doesn't sog. I am currently devouring a spinach, tomato, avocado, and green-olives-with-chillies salad, and am one very happy camper.
